updates for node 6

[Pomax]

fixes to sqlite3 and routes.js so that login can actually run on modern node (6+).

Oddly the fix in routes.js is for code that should not even work to begin with, because the env var that gets read in is a String, whereas the code pretend it's an array. Not sure why that didn't cause errors before, but it sure caused errors now =D

fixes #370, fixes #382
